摘要: Abstract With the help of 002 dark field images, Transmission Electron Microscopy is best adapted tool to follow microtextural evolution a coal during pyrolysis. Randomly distributed in coal, polyaromatic structural units cluster parallel coke form Molecular Orientation (MO) domains. The size histogram these MO domains fingerprint microtexture and permits us precisely determine solvolyzer role molecular component cross-linking effect oxygen atoms plastic stage.
